Webthe CF3Br boils [its boiling point at atmospheric pressure is -57.8 "C (-72.0 "F)]. The detonation of the squib also promotes nucleation in the N2-saturated agent. This turbulent, highly transient mixture of dense vapor and evaporating liquid travels through usually less than 3 m of pipe (but up to 24 m) from the storage location to the ... Bromotrifluoromethane, commonly known as Halon 1301, R13B1, Halon 13B1 or BTM, is an organic halide with the chemical formula CBrF3. It is used for gaseous fire suppression as a far less toxic alternative to bromochloromethane.
